Application filed July 18, 1917. Serial No. 181,308.

To all whom it m0" concern:

Be it known that we, ROBERT E. GALvrN. and HERBERT C. SGI-IUMACI-IER, citizens of the United States. residing at Rock Island, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Corn-Planters; and We hereby declare that the following is a full, ole. r, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is a novel improvement in corn planters and its Object is to provide an efficient. planting machine having novel means for actuating the seed dropping devices; novel marking devices; novel means for lifting the furrow devices and other novel features of construction and combinations of parts which will be hereinafter set forth in detail.

In the accompanying drawings we have illustrated a complete planter embodying each and all of the novel features ofthe invention, and which in connection with the accompanying description of such machine will enable others to manufacture and use the same; the essential features and combination of parts for which protection is desired being set forth in the claims following this description.

In said drawings:

Figure 1 is a top plan view of the complete machine. 7

Fig. 2 is a side elevation thereof, partly in section.

3 is a detail vertical section through the runner and seed box slide.

Fig. 4 is a detail section of the same parts at right angles to Fig. 3;

Fig. 5 is a detail top plan view of part of the connection between the steel tongue orback bone of the frame and the wooden or pivoted tongue.

Fig. 6 is a side view of Fig. 5.

Fig. 7 is a-detail plan view of the hinged connection between the lever6l and the tongue 62,

Figs. 8, 9, 10, 11, 12, 13, 14, 15, 16 and 17 are details.

.The main frame of the machine may be of any suitable construction, and is preferably made of bar iron and as shown is composed of side members F which are supported upon the main axle A by boxes or bearings B. Members F are connected in rear of the ax y In tr nsverse bar 1", and n r t of the axle by transverse bars F and F In front of bar F is a parallel bar F and to the bars F and F are attached the seed boxes or cans 28, which may be of any suit able construction, with the exceptions hereinafter noted, and at the outer sides of these boxes 28 are attached metallic frames F in which the marking devices are mounted.

The front bars F and F of the frame are connected by suitable brace bars F, and the front bar F of the frame has a hinged connection to the rear end of thewooden or pivoted tongue 62 as hereinafter explained, and also has a hinged connection with the main tongue member or backbone 58 of the frame, said member 58 extending longitudinally and centrally of the frame and connected at its rear end of the axle A and the tongue 62, being pivotally connected to the front end of member 58 as indicated at 64:.

The runners 30 are attached to the frame beneath the seed boxes 28 and are provided with furrow openers 30*, operating as usual. The frame is mounted upon the axle A which is carried by wheelsW and IV, which may be of any suitable construction.

In this machine all the automatic mechanical operations are performed by power derived from the wheels, preferably from the right-hand wheel W by means hereinafter explained, the device being set into or out of operation by means of a hand lever which throws one clutch member into or out of enga gement with another clutch member operated by the wheel.

In the example shown the hub 1 of the wheel WV is fastened to a sleeve 2 on axle A, and to the inner end of this sleeve is fastened a female clutch member 3. Sleeve 2 can turn freely on axle A and in the adjacent bearing 13 on the right side of the frame, and said sleeve is held in placeon the axle by a washer and nut a on the ends of the axle.

Slidably mounted on the axle and free to rotate thereon is a male friction member 4: which is pressed toward the female member by a coil spring 5 interposed between member 4 and a collar 6 fastened to the axle A. The clutch is controlled by a foot lever 7 pivoted on the tongue member 58. Said foot lever being connected by a link 7 to one arm of a bell crank lever 8 pivoted on member 5 3, the other arm. ofsaid lever 8 being con nected to the clutch shifting fork 9 which engages a .collar 10 looselysurrounding the I neck of the clutch member 4. The foot lever 7 is'guided by a bar 11 which has'a notch or slot '11 at one end into which the lever 7 can be engaged and hold .the'clutch disengaged or free when the lever 7 is disengagedbythe foot.

A key or pin 12, (see Figs. 1, 12, and 13), is fastened to the axle A adjacent the neck of the clutch member 4 which isdisengaged therefrom when the clutch members are in engagement. The clutch member 4 has three slots or notches '18 in its outer end which are preferably beveled adjacentthe key 12,

said notches conforming to the shape of the key 12 and adapted to engage therewith. The outer ends or mouths of these slots are preferably beveled to facilitate entrance of the key 12 thereinto when the clutch is thrown out regardless of the position of the.

slots .13 relative to the key 12 when the clutch member 4 moves'backward or inward,

to disengage member 3.

- To the clutch member 4 isrigidl'y attached a disk 15-whichis provided with three equidistant lugs or pins 14. These lugsor pins 14are adapted to engage the rear end of the trip lever 16 which is pivoted at 17 on aj support attached to the bar F of the frame.

' kernels so that they will enter the holes 29 The pins 14' are of'such length that'they will engage the trip lever 16 when the clutch members are in'engagement but will notstrike the trip lever 16 when the clutch members are disengaged. The slots 13 are made so that they readily engage with the key 12 and insure the correct relative position of lugs or pins 14 on a disk 15 hereintion of rest' shaft 20 and all parts connected therewith. A stop arm 22 is fastened to shaft 20 in position to engage with a stop 23 attached to the frame and arrest shaft 20 and all parts connected therewith in rest positlon.

A. gear 24 is fastened to each end of the shaft 20; and such gear 24 meshes with a rack25 attached to a sliding feed plate 26 operating in a housing 27 which forms the bottom of the adjacent seed box 28. This feed plate 26 preferably hasthree'longitudinal grooves 29 in its upper surface, and in each grooveis a hole 29 large enough to admit the desired number of seed kernels. The grooves'29. in the seed plate line up the readily. when the feed slot 26 is in normal,

rest,,positi0n in the bottom of the seed box,

28, the seed kernels can work into the holes 29 but cannot pass, through as they will rest on'the bottom of the housing 26 upon which the seed plate lies.

l Vhen the rear end of lever 16 is depressed by the engagement of a pin 14 therewith, it will through the described connections rock shaft 20, and, when the shaft is thus rocked the gear 24 thereon will operate racks 25 and move the seed plates 26 out, or back, bringing the holes 29" therein over the feed channel 30 in the runner-casting 30 and the kernels will drop through the channel onto a dropper 31 mounted in the casting at the lower end of the channel 30 near the bottom of the runner. Each dropper 81 is rocked at the proper time to drop the seed by means of an arm 81" connected to the rocker and in turn connected by a link 33 with an arm 20 on shaft 20.

The parts are so arranged that the dropper 31 is turned each time that the related slide 26 is brought back. At the time when slide 26 is brought back to allow the kernels in openings 29 to a fall into the channel in the runner 30, the pocket in the dropper 31 is turned downward. \Vhen at rest position pocket 32 is uppermost and receives the kernels just discharged from the sliding plate 26. When the slide 26 moves back dropper 31 is moved, so that pocket 32 is turned down to allow the kernels therein to drop into the furrow made by the opener 30*, and the kernels just dropped from the seed slide into the channel 30 are caught and retained. In this manner seed will be discharged at the proper times and each time that the lever 16 is rocked by a pin 14.

If for example, the wheel V is ten feet six inches in circumference, one revolution of the disk 15 when actuated by the wheel will oscillate lever 16 three times; thus for each revolution of the wheel V three hills of corn may be planted, the hills being three feet and six inches apart. Of course these proportions may be varied so as to planthills at any desired distances apart, and the invention is not restricted to any particular size of wheel nor to any particular number of pins or lugs 14 on the disk 15.

The mar/sing devices.

On shaft 20 is a sliding member 34 of a. preferably square-jawed clutch; which member 34 is caused to turn with shaft 20 by a key 36 but is movable freely into and out of engagement with an opposed clutch in ember loosely mounted on the shaft 20 and having an arm which is pivotally connected by a link36 to an arm 43 on a shaft 44 journaled in bearing-castings 44 attached to the frame.

The sliding member 34 of the clutch may be operated'by a hand lever 37 pivoted on the left hand side of the frame and connected by a link 38 to one armof a fork lever 39 which is connected to a loose collar 40 on a sliding clutch member 34:, lever 39 being pivoted on a bracket 39 attached to the frame, so that clutch 3-1 can be engaged or disengaged at will by properly shifting the lever 37.

The shaft 20 is prevented from moving endwise bymeans of the collar 22 and a collar 4E1 fastened thereto as indicated in Fig. 1. Shaft 44 is held in place longitudinally of the frame by-means of collars 17 and 4.5 which are rigidly fastened thereto adjacent bearings 44 as shown.

Casting 47 is provided with an arm which is adapted. to engage member 23 and arrest shaft 14: and parts connected therewith in rest or normalposition. The shaft 44: and parts connected therewith are normally held in, and returned to, rest position, by means of a spring 46 connected with the frame and to an arm on member 15, see Figs. 1 and 17.

To each end of shaft is are attached arms 48 each of which is connected by a link 49 to an arm 50 attached to a shaft 51 mounted in suitable hearings in the frame F. The shaft 51 being kept from longitudinal play in the framesF by arm 50 and collars 52. On the outer end of each shaft 51 is a gear 53 which meshes with a vertically disposed rack 54: mounted in a suitable guide 54c attached to a frame 52. To the lower end of each rack 54: is attached a marker 55 which may be adj ustably fastened thereto by set screws or other suitable means. In the example stated the point of each marker 55 would be twenty-one inches from the center of the adjacent runner 30 or one-half the distance between the adjacent rows.

When shafts 51 are at rest position and runners 30 are in the ground the points of the markers 55 drag on the ground as inclicated in full lines in Fig. 2 and make lines, light shallow furrows, therein. The line traced by one of the markers 55 on the out going trip should. be followed by the same marker 55 on the return trip, and thus will cause the desired distance between adjacent rows.

When the clutch 3% is engaged with member 35 so that shaft 44. is rocked by and from shaft 20, shafts 51 will be rocked and will through the gear connections depress the markers into the ground as indicated in dotted lines in Fig. 2 and cause them to dig holes three feet sixinches apart or the desired distance between the hills; this latter operation. however is intended to be performed only at the beginning and end of each row in order that the operator. can tellv where the first and last hills in the rows were planted.

Frame adjusting devices. 7 The forward part. of the frame towhich the runners 30 are attached is raised and lowered by a hand lever 56 pivoted on the tongue member '58 and adapted to be locked to a sector 57 in the usual manner. Hand lever 56 is connected by a rod 59 to one end of a bell crank 60 which is pivoted at its cen ter to the tongue member 58 and projects through a slot therein. The lower arm of thebell crank 60 is connected by two links 61, 61, to castings 61* bolted to the frame member F (see Figs. 5, 6 and 7).

The inner end of the front tongue 62 is pivotally bolted to the frame at the same point as at 62 in order to get a direct pull on the frame near the runners 30. Braces 63 are bolted to the tongue 62 and run back to and are pivotally connected with the frame at 65 in order to keep the frame in the right position. The tongue 6% is also bolted to the inner tongue member 58 at- 64k,

the bolt 6 f acting as a hinge joint.

The mud scrapers.

The mud scrapers are attached to a rod 67 mounted on. the rear bar of the frame, said rod having an arm 66 pivotally connected to one end ofa link 66, the other end of which is connected to a. foot lever 65, which is pivoted to the tongue member 58 adjacent the drivers seat S. A stop arm 68 on the scraper shaft 67 is arranged to engage the frame when at rest position, and acoil spring 69 normally holds the scrapers in rest position, away from the wheels.

Operation.

When the machine is in position to begin theplanting the operator should first throw in clutch 34F. which operates the marker 55. Then move. the tongue lift lever 56 to drop the furrow openers to the required depth for planting corn. Then release foot lever 7 from the notch in guide 11 to throw in the main clutch st. Then start the machine forward, and after it has dropped two or three hills pull lever 37 and disengage clutch 34. The markers 55 will then drag on the ground making lines one of which lines should be followed by the same marker making it on the return trip.

Vi hen about at the end of the row the operator should again throw in clutch 3t which will cause the marker to make holes in the ground. with which the markers must be brought into register on beginning the return trip. At the end of the row lever 56 should be moved so as to raise the markers and runners 30 clear of the ground while turning around. After turning around get the marker 55 directly over the hole made by the near marker then drop the frame, lowering the markers and furrow openers to the regular depth for planting, and proceed as on the previous row.

The markers -55-sh0uld be set ahead of.

the; channel 30 exactly. one-half the distance the wheel'travels before the drop is completed, The markers 55 make holes in the ground'atthe same time the corn is dropped.

After turning around the marker 55 should be brought directly above the hole] This determines the point where the clutch 4 should' be thrown in in order that the d ops on the return trip will be directly in line with the drops in the row just planted.

' In the drawings the dotted lines indicate the positions of the parts at the end of their active strokes and the full lines show the parts in rest. position. At the end of the planting operation when the clutch 4; is disengaged. the disk with the pins 14 thereon automatically sets itself in correct position to begin the next planting operation when the clutch is again thrown into engagement.

. This is due to the key 12 on the axle which causes the clutch member 4 to automatically shift itself, when disengaged from the clutch member 3, into position to reengage and resume operation immediately at the correct point.
